    Hi All,

    A question of chemestry and drug tests....

    How do different forms of amphetamine show up on drug tests? I think that Meth shows up as seperate from other amphetamines, and I am wondering how prescription drugs such as Adderall, Vyvanse, Ritalin, etc. report....as amphetamines or perhaps not at all???? (Vyvanse). Any factual information is greatly appreciated!

    Adderall and Vyvanse will show up as amphetamines on a drug test. Ritalin will not (as far as I know). The basic "pee in a cup" instant tests cannot distinguish between different types of amphetamines and may even give false positives/negatives depending on other components in your urine. However, if you're being drug tested by a clinic (and not, say, your parents), they will send a second sample (not the one adultured by the testing kit) of your urine to a lab to be tested using gas chromatography and mass spectrometry (GC-MS). This test can (and will) distinguish between Adderall, Vyvanse, and methamphetmine. Depending on how much the testing agency wants to pay (typically as little as possible), GC-MS is precise enough to identify relative concentrations of anything in the sample, so distinguishing between street d-amph and pharmaceutical d-amph is entirely possible.

    If you are prescribed Vyvanse, but test positive for Adderall (or meth), it will be considered a failure of the test.

    amphetamine will show up as amphetamines but not methamphetamine. Methamphetamine will cause a positive test result for methamphetamine and amphetamines, since the metabolite of methamphetamine is amphetamine.

    Vyvanse doesn't show up as amphetamines. Discovered this last week.

    Vyvanse has shown up as amphetamines on every UA I've taken for the last 9 months. Although, amphetamine metabolites are cleared from your body fairly quickly, so vyvanse might only show up for a day or two.

    This can't be true, Vyvanse gets processed into dextroamphetamine via liver/gastrointestinal action after it is ingested. Care to elaborate? Was this one of those unreliable home drug tests or a professional test?

    Or perhaps you were snorting it or injecting it? In which case the enzymes needed to convert it to amphetamine would not be used, hence the "less abuse" potential of Vyvanse.


    -----------

    OP, they both come out differently in urine. Further, they can use certain techniques that can determine if the drug came from a prescription drug or a street drug. D-Methamphetamine shows up in urine, using dextroamphetamine will not show methamphetamine in the urine instead it shows up partially unchanged in urine as well as other metabolites like benzoic acid.

    Does anyone know if it possible to pass a urine screen for one dose of Ritalin 30 hours after dose? Not a chronic user.

    No, I wasn't injecting or snorting it...I don't abuse it. Although I don't take it regularly either when I'm doing crystal. Since I don't take it regularly that is probably why the test came out the way it did.

    Does anyone know for sure if ritalin does not show positive for a urine test? Has anyone taken a urine test and it didn't show a positive ? I am routinely and randomly drug tested for illicit drugs , I don want to get a positive drug test because I am taking ritalin prescribed.

    How a substance shows up in a drug test or how long it can be detected is only a small part of the whole. Of greater concern is the plasma concentration of the drug, combined with the absorption and decay curves thereof, which is used to differentiate between legitimate use and illegitimate abuse of a drug.

    To expand on that, it's not the presence of amphetamines in a drug test alone that indicates addiction or abuse but rather the amounts of amphetamine in various concentrations in your plasma (blood), how fast those concentrations were achieved (indicating ROA) as well as the frequency, estimated timespan and estimated last administration. All of these factors can be revealed by evaluating absorption and decay curves as measured by comparing various concentrations of a substance in your plasma and comparing it to the absorption rate, bioavailability and half-life of the substance. Data that is already known for prescription drugs and most popular illegal substances out there.

    Or to state it as plain as possible, they can see from test results whether you swallowed, smoked, snorted or injected a drug, how much of the drug you have used thus, how often you used it and the last time you used it, more or less.

    Which means if you have a prescription for Adderall or Ritalin from your psychiatrist for ADHD or ADD, you would have nothing to worry about provided you were using your medication as prescribed. The test results will verify legitimate medical use. However, if you have a prescription for such medication but you're snorting crushed pills, taking larger doses than prescribed or taking doses more frequently than prescribed, to name a few examples, then such abuse will be easily revealed in your test results. You would probably have a hard time explaining such behaviour.

    Not having a legal prescription for Adderall or Ritalin would obviously raise alarm bells just by being present, regardless of quantity or any other considerations. The same would go for any illegal substances such as methamphetamine because the use of such is prohibited, no matter how 'therapeutic'. The detection times of such substances varies depending on the person and the substance involved. For example methamphetamine can be detected as long as a week after the fact, in some frequent users who use higher than normal doses on average.

    There is more detailed information about the most common substances regarding detection times and the subject of plasma concentration in this PDF document courtesy of labmed.yale.edu.

    If you are taking Ritalin as a prescribed medication, just make certain you have the prescription with you, and it should not be a problem. I once failed a drug test for a job I was applying for, because I forgot about cough medicine I had taken almost a week earlier, with codeine. Bottom line, I got the job after producing the prescription, even though it was my son's prescription, and not my own! This was careless on my part, and definitely not recommended (ADHD brain does it again!) But it is a case in point that they are looking for abuse, not proper prescription usage.

    rftn10: If you are legally prescribed a drug, an employer can't fire you for it, in the US that would be case for discrimination. Talk to your doctor and be honest with your employer, otherwise you're setting yourself up for a mess.

    i would be prescribed Ritalin but i do not trust my job. i have been working in the law enforcement field for over 10 years now. my position would be seen as a liability because of ignorance of what ADD is. i am a good officer , positive with the community and my superiors would just think i am not capable of doing the job even though i been diagnosed in my 3rd yr as a law enforcement officer. i currently take strattera but it works mild at best, and i tried Ritalin once and it worked instantly and i felt rejuvenated. i don't want to lose my job, so i opt to stay the way i am. i do take some vitamins like omega 3 which helps with brain fog, but for the life of me i cannot pass a test and get promoted. , i study for months and months yet i fail every promotional test , it seems like i never studied at all. my only issue with ADD is schooling. my job routinely drug tests me with a hair follicle test, however they claim they only test for illegal drugs and controlled substances. any advice?

    will Ritalin show up as an illegal drug? i am not looking to get canned for taking something legal.

    You have been in law enforcement for ten years and need to ask if Ritalin is a controlled substance? In the US? Yes, it is a Scheduled II controlled substance. It is illegal to take with out a prescription.

    i know Ritalin is a controlled substance, i stated my job tests for ILLEGAL drugs and controlled substances not the legal ones. what i meant to say is can ritalin on a hair or urine test show up as an amphetamine?

    can i risk not telling them and be secured. its unfortunate you have to be afraid of legal prescriptions

    what drug tests are being administered? You know, never mind, google the name of the drug test and read what comes up. You're looking for methyphenidate. Ritalin is more likely to show up as cocaine then amphetamine.

    there's no illegal controlled substances... they are controlled because they are legal.

    @rftn10

    If they are testing for "illegal drugs and controlled substances" then I think yes, they will be testing for ritalin. It is still a controlled substance and is a schedule two drug. I believe that the illegal drugs they are testing for would be exclusive to schedule one drugs (marijuana, lsd, ghb, etc). Being a controlled substance means exactly what the word suggest is means. It is a substance, that is "controlled". This should include otherwise illegal drugs unless the user can provide evidence of a legal prescription. Thus ritalin, adderall, vicodin, codeine, et al are all ILLEGAL unless you have a script.

    Why don't you just tell them that you take it?

    Who cares if they don't trust you, let them fire you for it. A good, hell any lawyer, would be able to show that you have been doing this job without issue for over 10 years, and been taking the ritalin for roughly the same amount of time. Proving that it doesn't affect your ability to adequately perform your job. I mean, that's why these things are prescribed, to allow people with normal disorders to pursue normal life's and careers. And if they fire you for it, then you could sue, big time!

    I imagine there has got to be other officers in your workplace that take ritalin or adderall, who have ADD/ADHD. Or even more likely, employee's who are on anti-depressants. The same fallacious argument can be made that depression negatively affects how they perform their jobs (although this is different because I doubt they test for these), but still the argument is the same.

    Ritalin is a common medication in the U.S., chances are someone else is taking it too. Even if not, I doubt anyone is really going to know what it is or what it's for when you show them a bottle that reads "methylphenidate". The only person that is going to know what that is would be the lab technician who is administering the test. And they could give a shit whether you are on it or not. They just need to know so that they don't write it up as a failed drug analysis.

    You really have nothing to lose by telling them. You don't even have to say what its for. Just be like "hey I'm not sure if this medication I am taking will affect the drug test, so here it is." and that's that.

    GC-MS (gas chromatography - mass spectrometry) tests will be able to identify methylphenidate (and it's metabolites). It won't show up at amphetamines, it will show up as methylphenidate. Typically GC-MS isn't the first test run, but if you get a false positive they will use GC-MS to verify or nullify the initial positive results (and you will eventually have a false positive). At this point you risk them identifying methylphenidate. Since they won't be looking for methylphenidate specifically, they might not discover it, but the test is fully capable of identifying methylphenidate.

    Testers can identify Tylenol (acetaminophen) in cases where an overdose is suspected to be a cause of death. Legal or illegal, GC-MS is used to identify almost anything under the sun. If they're looking for it, they will find it.
